Summer, 198?. I was 19, a good-enough looking lad but still a bit green behind the ears. Invited to visit friends who had moved to another town, didn\'t have a car so train it was. Train was just about empty, had a double bench seat all to myself. Settling down to read when I heard raised voices through the door in the carriage-end. Couldn\'t make out what they were saying over the clatter of the train and after a minute or two the voices seemed to move away into the next carriage. I read my book. The door behind me suddenly opened and a woman was standing there. She was tall and lean. Blonde from a bottle, green eyes, thin gold chain, thin white cotton top under a fitted white jacket, short marble-wash denim skirt (it was the \'80s...), long bare legs, white clogs. No bag. She was maybe late-twenties/early thirties? Good looking but in a hard sort of way. She also looked angry and emotional, like she might recently have been crying. A faint but distinct whiff of drink entered the carriage with her. Even to my inexperienced eyes, she looked like trouble. I wasn\'t sure whether to fancy her or be scared. She looked up and down the carriage and then sat down in the two vacant seats facing me. Oh shit. I carried on reading, hoping she wouldn\'t notice me. She restlessly stared at the floor and out the window. I peeked at her legs which were quite close to mine. My cock stirred, I couldn\'t help it. Then she looked at me. Didn\'t look away. I was beginning to feel uneasy when a noise at the carriage door drew her attention. She got up, went out and the raised voices I\'d heard before started up again. This time ending with a very loud \"fuck off, just fuck off. I never want to see you again\". She came back in, crying, pulled the sliding door closed hard behind her. Back on the seat, she stared out the window again and seemed to compose herself. Then she turned to me, \"what\'s your name?\" I told her. \"I\'m Claire\", she said. I asked her if she was ok, she said that no she wasn\'t really but things would get better. I said I hoped so and dithered about going back to my book. She looked at me strangely, leaned closer and asked if she could ask me something. \"Do you find me attractive?\" Gulp. \"Um, yes\" I said, shitting myself. My cock stirred again and I shifted in my seat to try and hide it. She spotted this and gave me a tiny half smile. Christ, I\'d done ok with girls at school and after but this was not a girl, this was a real and disturbingly direct woman. I was floundering. She shifted forward again on her seat so her knees were pushed up against mine. Her legs were slightly apart and my eyes drifted up her thighs, I couldn\'t stop them. She spoke again, \"Do you mean it? That guy I was talking with out there is my fiance and he doesn\'t seem to\". I must have looked puzzled because she went on, \"he doesn\'t give me enough sex\". Dangerous waters, I thought but interesting! \"I mean\", she went on, \"I\'d go with you. You\'re a good looking guy, that\'s why I sat in this empty seat and not one of the many others in here\". This kind of thing just didn\'t happen in my little world. I blushed but my cock was bulging and eventually the hormones won. Shaking slightly, I put my hand on her knee. My skin on hers felt like a lightning bolt and at some level I just knew that this was an important moment in my life, crossing the barrier from vanilla adolescent fumblings to something else. Her face was close to mine as I looked up at her. \"I do mean it\", I said awkwardly, \"I\'m glad you sat in this seat.\" Our eyes together, she took my hand from her knee and cupped it under her chin. Slowly she opened her lips and took my thumb into her mouth. I thought I would come right there in my pants. Still with her eyes on mine, she took my hand from her face and placed it on her left tit and, using my forefinger and wet thumb, squeezed her nipple surprisingly hard. She shifted on her seat and gave a tiny sigh. I looked down and could see her nipple standing rigd and past that her small skirt which had slowly ridden higher and higher as her legs splayed in between mine and the train joggled us from side to side. She squeezed her nipple hard again with her own hand and groaned. \"Touch yourself\", she said. I was reluctant to get my knob out in an open train carriage but she sucked on my thumb again and said, \"if you don\'t, I will get up and leave and you won\'t ever see me again\". My mind went to mush and I sat back in the seat and unzipped myself. My cock is a decent 7\" but somehow it looked like it had swolen half as big again and was absolutely throbbing. I was afraid to touch it in case it went off. She had no such qualms and quickly knelt in front of me, looked up at me and started to kiss it. Little dry kisses starting at the base and working up to the tip. And then she was gone, sitting back on her own seat. \"Now, touch yourself. Show me how much you want me.\" I had no choice and slowly started to wank. I went as gently as I could to prolong the pleasure but I was almost relieved when I finally did come and I could put myself away again. But no, it wasn\'t that simple. one of her hands went back to her nipple which she tweaked and pulled as I wanked. The little noises she made and the expressions on her face were great for me as I wanked, she was so uninhibited. I didn\'t notice at first but her other hand had moved to her crotch and was rubbing the front of her panties. Soon it was inside her pants and the noises became more intense. That was too much for me and I popped my cork. She seemed to be even more turned on by the sight of it and knelt in front of me again. One hand still at her pussy, the other scooped up some of my cum and stickily rubbed it all over my shrinking cock. As my glazed eyes and animal lust faded, I began to wonder how I was going to get out of this situation but she had other ideas. She stood up with her legs either side of mine and said, \"Eat it. Make me come like you did\". I was in two minds at first but I could feel the heat of her body so close and the smell of her was wonderful. I reached up under skirt and pulled her knickers down to her knees. Then pushed her skirt up over her hips and looked at what was in front of me. She was neatly trimmed ( a first for me ) and had a beautiful symmetrical mound, good big hooded clit and delicate little pink lips. And God was she wet. She twitched when I put my hand on her inner thigh and murmured to me that it felt good. She continued with a stream of low words and groans as my hands moved on her. I was gentle at first with an exploratory finger finger between her lips but the bolder I got the more she seemed to like it. Fingers were just a warm up though. I reached around and put my hands on her bum cheeks, pulling them up and apart slightly. She moaned as I slid my right 4th and 5th fingers in between her lips from behind, she then put her knees on the seat either side of me to gain some height and pushed herself into my face. I ran my tongue up between her lips and was soon at her clit, nibbling gently. As her whole body started to quiver, I put a finger inside her and then another and then another. She was oozing and her quivering grew more intense and then seemed to reach a plateau. One of her hands was suddenly behind my neck and she pulled me harder into her. \"Bite me\", she said. Bloody hell... I put my tongue away and gently nipped her hooded clit with my teeth. Her body shook, she groaned. I did it a few more times with the same result. Then she said \"That\'s great but now do it really hard so I can come\". I worked at her clit with my tongue and lips, bringing the core out from its cover and placed my teeth on either side. A little pressure and she really started to squirm. A little more and the squirm almost became a spasm, her breathing quick and hard now. Suddenly with my next bite her body suddenly went rigid and I could feel her abdominal muscles pulsing as she gripped my fingers inside her. Slowly, she crumpled on top of me like a rag doll, still giving the occasional twitch. My little 19 year-old mind was blown wide open. As she sorted herself out and got off me, it became obvious that my cock was ready for more (one good thing about being 19...). She still had that glint in her eyes too and without a word she stood up, took my hand and pointed. Together we snuck out into the carriage-end and into the toilet. My inhibitions had taken a back seat finally and my hands were all over her even before we\'d locked the door. Our clothes were soon in a heap on the floor and I could really look at her. She had a good tight body, not too curvy but firm bum and shapely if small tits. I wanted to fuck her. I guess she was happy enough with what she saw of me too as the hungry look in her eye said one thing and one thing only: Sex. Now. On her knees in front of me, she slowly took my whole length in her mouth and licked off my dried cum from before. Her tongue knew some tricks and soon fresh stuff was oozing from my tip which she licked off too. I pulled her up standing, backed her against the sink ledge and pushed myself up against here. Her nipples were hard against my chest and my cock was nudging at her flat stomach. I lifted her onto the ledge so she could sit on the edge with her legs open. Mmmmmmmm, just the right height. Now my cock was nudging her pussy and leaving shiny trails of my goo. She had one arm out behind to steady herself and was rocking her hips to try and catch the tip of my cock as I cupped her tits and began to mess with her nipples. The harder I squeezed, the more she seemed to like it and her demands for me to fuck her grew more urgent. I didn\'t need much persuading and soon I was lined up and ready to push my way in. She licked her palm and fingers and gripped my cock before pulling her hand back onto herself where she began to wank busily. I put my hands on her hips and pushed the head of my cock just between her lips. She moaned gently and moved her hips to open herself up more. Her eyes half closed, she whispered \"Now, put it in me now. Please\". That final \"please\" did something in my brain and my need clicked with hers. A combination of my cock and her hand soon brought her off and she came noisily. She still wasn\'t done though and said to me that she needed another orgasm and that I had to do it from behind. I was beyond words at that point and soon found myself following her instructions and blindfolding her with our discarded clothes. I soon got the gist and pushed her hard down over the sink and entered her roughly from behind. Her pussy seemed to grip my cock even better in this position and it felt incredible. Her tight little bum was pushing back against me as I fucked her and she sensed that I was getting close to orgasm. I pulled her head back and was gripping her throat tight while I fucked her as hard as I could. \"Make me come again!\", she said, \"fuck me fuck me fuck me make me come againmakemecomeagainagainagain...\" I could feel her hands working on her clit now too and suddenly she came with a judder and much wetness. I let go too and buried my cum as far up her as I could. I could feel her juices running down her legs and onto me. It wasn\'t comfortable or relaxed in any way but we were spent and neither of us could move for several minutes. Eventually we cleaned ourselves up as best we could, got dressed and went back to our seats. Or at least I did. She stayed in the toilet after I left, saying she\'d be along in a minute but never appeared. After a while I went and checked the toilet but she was gone. I never saw her again.
